1 Introduction

This document defines EP06 module and describes its air interface and hardware interfaces which are

connected with customers’ applications.

This document can help customers quickly understand the interface specifications, electrical and

mechanical details, as well as other related information of EP06 module. To facilitate its application in

different fields, reference design is also provided for customers’ reference. Associated with application

note and user guide, customers can use the module to design and set up mobile applications easily.



1.1. Safety Information

The following safety precautions must be observed during all phases of operation, such as usage, service

or repair of any cellular terminal or mobile incorporating EP06 module. Manufacturers of the cellular

terminal should send the following safety information to users and operating personnel, and incorporate

these guidelines into all manuals supplied with the product. If not so, Quectel assumes no liability for

customers’ failure to comply with these precautions.

Full attention must be given to driving at all times in order to reduce the risk of an

accident. Using a mobile while driving (even with a handsfree kit) causes

distraction and can lead to an accident. Please comply with laws and regulations

restricting the use of wireless devices while driving.

Switch off the cellular terminal or mobile before boarding an aircraft. The operation

of wireless appliances in an aircraft is forbidden to prevent interference with

communication systems. If the device offers an Airplane Mode, then it should be

enabled prior to boarding an aircraft. Please consult the airline staff for more

restrictions on the use of wireless devices on boarding the aircraft.

Wireless devices may cause interference on sensitive medical equipment, so please be aware of the restrictions on the use of wireless devices when in hospitals, clinics or other healthcare facilities.

Cellular terminals or mobiles operating over radio signals and cellular network

cannot be guaranteed to connect in all possible conditions (for example, with

unpaid bills or with an invalid (U)SIM card). When emergent help is needed in such

conditions, please remember using emergency call. In order to make or receive a

call, the cellular terminal or mobile must be switched on in a service area with

adequate cellular signal strength.

The cellular terminal or mobile contains a transmitter and receiver. When it is ON, it

receives and transmits radio frequency signals. RF interference can occur if it is

used close to TV set, radio, computer or other electric equipment.

In locations with potentially explosive atmospheres, obey all posted signs to turn

off wireless devices such as your phone or other cellular terminals. Areas with

potentially explosive atmospheres include fuelling areas, below decks on boats,

fuel or chemical transfer or storage facilities, areas where the air contains

chemicals or particles such as grain, dust or metal powders, etc.

Figure 4: Reference Circuit of (U)SIM Card Interface with a 6-pin (U)SIM Card Connector

In order to enhance the reliability and availability of the (U)SIM card in customers’ applications, please

follow the criteria below in (U)SIM circuit design:

⚫ Keep placement of (U)SIM card connector to the module as close as possible. Keep the trace length

as less than 200mm as possible.

⚫ Keep (U)SIM card signals away from RF and power supply traces.

⚫ Keep the trace width of ground and USIM_VDD no less than 0.5mm to maintain the same electric

potential. The decoupling capacitor of USIM_VDD should be less than 1uF and must near to (U)SIM

card connector.

⚫ To avoid cross-talk between USIM_DATA and USIM_CLK, keep them away from each other and

shield them with surrounded ground.

⚫ In order to offer good ESD protection, it is recommended to add a TVS diode array with parasitic

capacitance not exceeding 50pF. The 22Ω resistors should be added in series between the module

and the (U)SIM card so as to suppress EMI spurious transmission and enhance ESD protection.

Please note that the (U)SIM peripheral circuit should be close to the (U)SIM card connector.

⚫ The pull-up resistor on USIM_DATA line can improve anti-jamming capability when long layout trace

and sensitive occasion are applied, and should be placed close to the (U)SIM card connector.

3.5. USB Interface

EP06 provides one integrated Universal Serial Bus (USB) interface which complies with the USB 3.0/2.0

specifications and supports super speed (5Gbps) on USB 3.0, high speed (480 Mbps) and full speed (12

Mbps) modes on USB 2.0. The USB interface is used for AT command communication, data transmission,

GNSS NMEA output, software debugging, firmware upgrade and voice over USB*.



The following table shows the pin definition of USB interface.

module and also close to each other. The extra stubs of trace must be as short as possible.

The following principles of USB interface design should be complied with, so as to meet USB 2.0 & USB

3.0 specifications.

⚫ It is important to route the USB signal traces as differential pairs with total grounding. The impedance

of USB differential trace is 90Ω.

⚫ For USB 2.0 signal traces, the trace length difference of the differential pair should be less than 2mm.

⚫ For USB 3.0 signal traces, the trace length difference of each differential pair (TX/RX) should be less

than 0.7mm.

⚫ Do not route signal traces under crystals, oscillators, magnetic devices or RF signal traces. It is

important to route the USB 2.0 & 3.0 differential traces in inner-layer with ground shielding on not

only upper and lower layers but also right and left sides.

⚫ If a USB connector is used, please keep the ESD protection components to the USB connector as

close as possible. Pay attention to the influence of junction capacitance of ESD protection

components on USB 2.0 & 3.0 data lines. The capacitance value of ESD protection components

should be less than 2.0pF for USB 2.0, and less than 0.4pF for USB 3.0.

⚫ If possible, reserve a 0Ω resistor on USB_D+ and USB_D- lines, respectively.


3.6. PCM and I2C Interfaces

EP06 module supports audio communication via Pulse Code Modulation (PCM) digital interface and I2C

interface.

NOTE

S



The PCM interface supports the following modes:

⚫ Primary mode (short frame synchronization, works as either master or slave)

⚫ Auxiliary mode (long frame synchronization, works as master only)

In primary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising

edge. The PCM_SYNC falling edge represents the MSB. In this mode, the PCM interface supports

256kHz, 512kHz, 1024kHz or 2048kHz PCM_CLK at 8kHz PCM_SYNC, and also supports 4096kHz

PCM_CLK at 16kHz PCM_SYNC.

In auxiliary mode, the data is sampled on the falling edge of the PCM_CLK and transmitted on the rising

edge. The PCM_SYNC rising edge represents the MSB. In this mode, PCM interface operates with a

256kHz PCM_CLK and an 8kHz, 50% duty cycle PCM_SYNC only.

EP06 supports 16-bit linear data format. The following figures show the primary mode’s timing

relationship with 8kHz PCM_SYNC and 2048kHz PCM_CLK, as well as the auxiliary mode’s timing

relationship with 8kHz PCM_SYNC and 256kHz PCM_CLK.

6.8. Thermal Consideration

In order to achieve better performance of the module, it is strongly recommended to comply with the

following principles for thermal consideration:

⚫ On customers’ PCB design, please keep placement of the module away from heating sources,

especially high power components such as ARM processor, audio power amplifier, power supply.

⚫ Do not place components on the PCB area where the module is mounted, in order to facilitate adding

of heatsink.

⚫ The reference ground of the area where the module is mounted should be complete, and add ground

vias as many as possible for better heat dissipation.

⚫ Add a heatsink on the top of the module and the heatsink should be designed with as many fins as

possible to increase heat dissipation area. Meanwhile, a thermal pad with high thermal conductivity

should be used between the heatsink and module.

⚫ Add a thermal pad with appropriate thickness at the bottom of the module to conduct the heat to

PCB.

1. Make sure that customers’ PCB design provides sufficient cooling for the module: proper mounting,

heatsinks, and active cooling may be required depending on the integrated application.

NOTES



2. In order to protect the components from damage, the thermal design should be maximally optimized

to make sure the module’s internal temperature always maintains below 105°C. Customers can

execute AT+QTEMP command to get the module’s internal temperature.

3. For more detailed guidelines on thermal design, please refer to document [5].
